1) add ui and backend support for "log into this account at startup". all that is missing is the code to actually do the logging in at startup. that comes next.
2) hide the user name for news servers in the account manager.
3) fix ui to allow users to edit the username and hostname for a server, but disable it until the back end can handle a live swap of those values.
